Polaronic and Electrochemical Signatures in Group IVB (Ti, Zr, Hf) Oxides: Unified SKP–DFT Insights for Tunable Transport in Energy and Electronic Devices

Advanced Functional Materials, EarlyView.
Charge carrier concentration and mobility in TiO2, ZrO2, and HfO2 powder films are experimentally mapped as a function of temperature. The results uncover polaron‐mediated transport regimes and field‐activated conduction, enabling the design of oxide‐based electronic and energy devices with thermally tunable functionality.

Gated PN Junction in Ambipolar MoS2 for Superior Self‐Powered Photodetection

Advanced Functional Materials, EarlyView.
A high‐quality gated pn junction based on ambipolar molybdenum disulfide (MoS2) is demonstrated by employing a partial‐gate structure and a Pt bottom contact that forms a semi‐van der Waals interface, facilitating efficient hole injection into the channel.

Smart Nanogels as Enzyme‐Driven Nanomotors for Navigating Viscous Physiological Barriers

Advanced Functional Materials, EarlyView.
Two families of urease‐powered nanomotors (NMs), with and without a p‐(2‐hydroxyethyl methacrylate) (p‐HEMA) shell, have been successfully prepared. Both types exhibit effective motion in highly viscous synovial fluid media at low urea concentrations (25 mM).

High Dynamic Range Thin‐Film Resistive Flow Sensors for Monitoring Diverse Biofluids

Advanced Functional Materials, EarlyView.
Thin‐film resistive flow sensors with thermoresistive and piezoresistive mechanisms are developed for biofluid monitoring. Fabricated using biocompatible materials and laser micromachining, the devices achieve sub‐millimeter dimensions and a broad dynamic range.

Domain Nucleation and Growth in an Epitaxially Grown Wurtzite Ferroelectric

Advanced Functional Materials, EarlyView.
Ferroelectric domain nucleation and growth in epitaxial wurtzite (Al, B, Sc)N films are visualized through in situ transmission electron microscopy. Domains initiate near the bottom electrode and propagate laterally with zigzag walls, while unswitched regions remain near the electrode interfaces.
